I have 3.3 acres and am currently paying someone else to cut my lawn once every 2 weeks. However, the grass grows quickly and I am planning to buy my own mower and cut the grass once per week since I will save money as compared to paying someone to cut it once per week. I was looking at a Scag Tiger Cub 48" wide ZTR for $5800 but this afternoon I discovered that Sears has Swishers with similar horsepower and widths for much less money. I'm concerned with long term quality and speed of mowing. I believe the Swisher has a top speed of 6 mph and the Scag a top speed of 10, but can I actually mow faster than 6 mph? How much longer will the Scag last without breaking compared to the Swisher? Any other disadvantages to buying a Swisher besides mowing speed and long term quality? I will attach a picture of my front lawn for reference. Thanks.
